Abstract
Official abstract text for this publication.
A latch mechanism for a surgical instrument includes a lever moveable from an initial position to an actuated position for moving an end effector assembly from a first to a second state. A pin extends from the lever. A cantilever spring is operably engaged to the housing of the instrument. A pin track member is operably engaged to the cantilever spring at a free end thereof. The pin track member is configured to permit translation of the pin therealong between a first position corresponding to the initial position of the lever and a second position corresponding to the actuated position of the lever. The pin is configured to translate from the first to the second position along a first path and from the second position back to the first position along a second path and is configured to be releasably retained in the second position.
